| In order to solve complex large-scale dynamic optimization problems online and in real time, this paper
proposes a distributed dynamic optimization scheme called receding cooperative game optimization (RCGO) based on
dynamic games. Firstly, based on the receding horizon optimization framework, the scheme decomposes original complex
large-scale dynamic optimization problems into several simple small-scale local dynamic optimization subproblems, which
reduces the computational complexity and ensures the real-time solutions of the dynamic optimization problems. Then,
based on dynamic games, the iterative decomposition method is proposed to solve local dynamic optimization subproblems,
and the system stability under the RCGO scheme is analyzed. Finally, this paper uses a chemical process network as
a simulation case. Based on the RCGO scheme, the optimal operations of the network with the maximum economic
benefit are obtained. The optimization results show that when solving complex large-scale dynamic optimization problems
online, the RCGO has more advantages than the traditional centralized dynamic optimization scheme in terms of the system
economic benefit, closed-loop control performance and real-time optimization solution. |
